Abstract

"SISTEMA DE CONTROLE PARA PROCESSAMENTO A LASER DE UM MATERIAL, E, REDE NEURAL PARA DETECTAR EVENTOS EXTRAORDINáRIOS DENTRO DE UMA CORRENTE DE DADOS ENTRANTE" . é provido um sistema de controle para processamento a laser de um material, o sistema compreende um sensor para receber emissões eletromagnéticas de uma zona de solda; um subsistema de lógica confusa para processar saídas do citado sensor diretamente, para produzir um sinal de saída de qualidade de solda; e um sub sistema de rede neural usando freq³ência de dados de entrada a partir das saídas do citado sensor e citado sinal de qualidade de solda para desenvolver um sinal de controle de parâmetro de solda, por meio do qual a rede neural é capaz de detectar eventos extraordinários na corrente de dados "que entras" , enquanto o controlador de lógica confusa é capaz de detectar tendências na corrente de dados "que entras".
